The Wash? Is it worth it?

I am dying to get onto salt water but living in Leicester I could not be further from the sea

The Wash is my nearest saltwater but my memories of it are of a massive mud flat. Mind you that is from being a kid at Hunstanton 40+ years ago.

Is it worth a trip?Is there anyone here who fishes the area?Where would be a viable place to launch?What state of tides would I have to plan for to save a 2 mile hike in the mud?What would I be fishing for?

All my serious sea fishing has been done going west, mainly on the LLeyn ( God's Country ) so the North Sea is virgin territory that has never really appealed but I suppose I should not just dismiss it without asking for advice.
